19 Claims. i

This invention relates to a depository of the type generally referred to as a night depository." More particularly this invention relates to a depository which automatically issues receipts for deposits and to a mechanically operated receipt issuing night depository or the like.

The depository of this invention is of the type generally described in the copending application of John J Murtaugh, Jr., Serial No. 52,481 filed October 2, 1949.

An object of this invention has been to provide a night depository in which a receipt is issued for each package deposited therein.

A further object of this invention is to provide a night depository which prints indicia on a package deposited therein and automatically issues a receipt bearing the same indicia as are printed on the package.

A further object of this invention is to provide a receipt issuing night depository which is wholly mechanical in operation and requires no electrical or hydraulic connections.

A further object of this invention is to provide a receipt issuing depository which can issue a receipt only after a package has been inserted therein.

A further object of this invention is to provide a receipt issuing depository which cannot be opened so long as a package is disposed within the depository so that a package cannot be removed once it has been stamped and, if a package becomes lodged in the depository, the package cannot be reached by a subsequent depositor.

A further object of this invention is to provide a receipt issuing depository in which the receipt acts as a, printing plate for printing indicia on a package inserted in the depository prior to issuance of the receipt.

A further object of this invention is to provide a receipt issuing depository which folds the receipt before issuance to protect inked indicia thereon.

Briefly this invention provides a receipt issuing depository which employs receipt tickets having indicia embossed thereon. The indicia are automatically inked when the depository door is opened and the indicia on the ticket are impressed on a package when the package is disposed in the receptacle of the depository. Then, the ticket is issued to the depositor to make a record of his deposit while the package drops into a vault. Stops are provided so that once the indicia have been impressed on the package, the package cannot be removed from the'depository, and the depository cannot be reopened until the package falls into a vault. Further, a disengaging mechanism or clutch is provided to prevent the issuance of a ticket when no package has been placed in the receptacle of the depository. The ticket is folded with the inked indicia inside the folded ticket before the ticket is issued to protect the inked indicia. The device is wholly mechanical in operation requiring no electrical or hydraulic connections so that the depository cannot be put out of working order by power failures, fluid leaks, or the like.

The above and other objects and features of the invention will in part be obvious and will in part be apparent from the following detailed description taken in connection with the accompanying drawings, in which:

In the following detailed description and the drawings. like reference characters indicate like parts. 4

In Fig. 1 the outside panel of the depository is indicated at 39. The panel 30 may be mounted in any suitable manner in an outside wall 30' of a bank or other building where deposits are to be made in the absence of any attendant. The panel 30 is provided with a coin opening 3| through which an appropriate coin may be inserted for releasing the door of the depository. A handle 32 projects outwardly from the panel 30. A slot 33 is provided in the panel through which a receipt is issued when a deposit is made.

The handle 32 actuates two segment arms 52 and 95 (Fig. 29) which are attached thereto and can be swung in and out of the depository with the handle 32 to actuate the mechanism of the depository. When the handle 32 is pulled outwardly of the depository, a door 34 (Fig. 15) is uncovered behind the handle, and, when the handle is pulled fully out, the door 34 is opened to reveal a slot 36 into which an appropriate package or envelope 35 (Fig. 10) may be inserted. When the handle is pushed in, the door 34 closes to cover the slot 36 and prevent removal 4 of the package. While in the slot 35, the package may be stamped with appropriate indicia. The indicia are provided by tickets 31 (Figs. 23 and 24) which are fed through a ticket holding slot 33 (Figs. 5 and 10) inside the receptacle. Each ticket. as shown in Figs. 23 and 24 bears embossed indicia 39 and the indicia are exposed in the slot. The indicia 33 are inked while in the slot and the package and inked indicia are brought together inside the receptacle to print on the package the same indicia which appear on the ticket. Then, as the handle 32 is pushed inwardly, the package is released and the ticket is dispensed through the ticket slot 33 to form a receipt and record of the deposit transaction. When the handle is fully in, a cross bar 40 (Fig. 11) attached to the handle 32 covers the door 34 and the depository is locked shut. The tickets are folded before being dispensed so that the inkedindicia are not exposed but are covered when dispensed.

The device which has to this point been described in general terms will now be described in greater detail.

The handle 32 is released by inserting a coin through the coin slot or opening 3i. As indicated in Fig. 4, as a coin 4! is inserted through the coin slot 3|, the coin raises the front or forward end of a triangular head or block 42 hearing on a roller 43 (Figs. 4 and 12) at the forward edge of the head 42 to raise the roller 43 and swing a release arm 44 (Figs. 3 and 4) which'is attached to a second triangular head 46 (Figs. 3 and 5). When swung downwardly, an end 41 (Fig. 4) of the release arm 44 comes between stop roller discs 48 (Figs. 4 and 13) and bears on an axle pin which extends between the discs to depress the discs against a spring pressed.

plunger 49 forcing the discs past the plunger into a socket 5| at the outer side of the plunger.

As shown most clearly in Fig. 6, when the disc 48 is in the socket 5|, the handle 32, a radial arm 5|, and a segment arm 52 which extends between the handle 32 and the radial arm 5| can be pulled outwardly, while when the disc is in a socket 53 on the inner side of the plunger 49, the handle 32, radial arm 51', and segment arm 52 may be pushed downwardly. However, if the direction of movement of the handle is reversed midway in a stroke, the discs 48 ride upwardly along one of a pair of sloping surfaces 54 to bind against a curved lower surface 55 of an inwardly extending bar 51 which forms a part of and is integral with the front panel 30.

. The release arm 44 swings through a slot 51 in the bar 51 (Figs. 6 and 13) for releasing the discs. The plunger 49 holds the discs 48 in contact with the surface 54, and when the handle is urged in a direction to cause the discs to ride up one of the sloping surfaces 54, the handle is locked and cannot be advanced. When the handle 32 is pulled fully out. the discs 48 come against a pin 58 on the underside of the curved surface 56 and are automatically reset in the socket 53 so that the handle and arms attached thereto may be pushed inwardly. When the handle 32 and arms have been pushed fully in, the disc 48 comes to rest in a curved slot 6| on the underside of the bar 51, and the handle and arms are locked against outward movement until released by the pivot arm 44.

Ordinarily, the pivot arm 44'may be caused to release the disc 48 whenever a coin is inserted through the coin opening 3|. However, if a package becomes wedged in the slot 35, as

48, as already explained. However, if an envelope is stuck in the slot, the arm 83 comes to rest at the position shown at 880 in Fig. 20 abutting the stuck envelope 82.

'As shown in Figs. 3, 5, and 22, the triangular heads 42 an'd 48 are connected by three ball bearing connections 84, each of which ball bearings is disposed in conical sockets in adjacent faces the triangular heads, and the heads can be separated against the force of a spring 88. It a coin is inserted into the coin opening when an envelope is stuck in the receptacle 38, the arm 83 prevents turning of the heads 42 and 48 audiciently to cause release 01' the discs 48 and, as the coin is pushed into the coin slot, the heads 42 and 48 are driven apart, the head 42 moving away from the head 48 as the ball bearings 84 advance out of their sockets until the head 48 is behind the coin slot 3| preventing further advance 01' the coin. The head 42 can advance until a stop sleeve 88 (Fig. 22) engages a bracket arm 88' which limits sidewise movement of the head 42. The stop sleeve 88 acts to limit separation of the heads so that the heads cannot be separated sumciently to permit the ball bearings 84 to ride out of their sockets.

As long as the heads 42 and 48 are not forced apart, suiilcient space is provided between the head 42 and a block 88", which is attached to the panel 38 on the other side of the coin slot 8|, to permit a coin to pass therebetween. However, when the heads 42 and 48 are separated, the head 42 moves behind the coin slot 3| and prevents further insertion of the coin. If an attempt is made to further rotate the head 42 by means of a tool other than a coin when the heads have been separated. the head 42 will swing against the block 68" to limit the turning of the heads.

So long as there are tickets 31 in a ticket holding rack 81 (Figs. 2 and 3) it is possible to insert a coin at least part way into the coin opening. However, when all tickets have been removed from the rack 81 a pin 88 moves to the left as shown in Fig. 3 through a block 86" and across the coin opening 3| to close the coin opening. The pin is carried by a bell crank 89, and a spring 1| constantly urges the bell crank upwardly to drive the pin 88 across the coin opening. However, as long as tickets remain in the rack 81,,a lever arm 12 is held up, as shown in Fig. 25 by the lowermost ticket. As shown in Fig. 3, the lever arm 12 is carried by link 13 which is pivoted on the panel 38. and when the left hand end of the lever arm 12 is released, it falls into a slot 14 (Fig. 25) and the right hand end of the lever arm 12 rises permitting a pull rod 18 attached to the bell crank to rise and re: lease the bell crank to drive the pin across the coin opening 3|. The coin slot 3! is 'closed by the pin 88 before all tickets are expended so that a new strip of tickets can be attached to the free end of the old strip without need for rethreading tickets.

As the handle 32 is pulled outwardly, a roller 11 (Figs. and 13) attached to the segment arm 82 engages a pivoted ink roller actuator arm 18 and, as the handle is pulled further out, the

actuator arm is swung counterclockwise as shown 1 in Fig. 5 from the position shown in full lines to the position shown in dotted lines at 18a. The actuator arm 18 drives an arm 18 which carries compound planetary gears 8|, 8| and 82 (Figs. 3 and 5). The gear 8| swings about a stationary or sun gear 83. which is a part of a support hub 83' which is attached to the panel 38. The gears 8| and 8| rotate together as shown in Figs. 3 and 13. The planetary gears rotate as they swing about the sun gear, and an inking roll 84 turns and swings with the gear 82. The

I roll 84 carries an end of an inking ribbon 88.

The other end of the ribbon 86 is attached to a spring loaded ink holding roll 81 which is retatably mounted on a stationary ribbon roll bracket 81'. As the planetary gears and the roll 84 swing about the sun gear 83 the ribbon is wound upon the roll 84 and, at the lowermost point reached by the roll 84, the roll 84 and the ribbon on the roll 84 come against the indicia on a ticket in the ticket holder 38 to ink the the indicia as indicated in dot-dash lines in Fig. 5. The gearing is arranged so that the inking roll has a rolling motion as it crosses the ticket, rolling in a hypocycloidal manner over the ticket and indicia without dragging over the ticket. Then, as the handle is pulled further out, the roller 11 passes beyond the actuator arm 18, and a spring 88 returns the planetary gears to the position shown in full lines in Fig. 5, While a spring 89 (Fig. 3) rewinds the ribbon on the roll 81. A leaf spring 9| limits the return of the actuator arm 18 and the leaf spring 9| sets the actuator arm 18 in position to be caught by the roller 11' during the next operation of the depository. On the return stroke of the segment arm 52 and roller 11, the actuator arm 18 is pushed backwardly against the leaf spring and a lost motion connection shown in Fig. 26 between the actuator arm 18 and the gear carrying arm 13 permits the actuator arm to swing backwardly against the leaf spring without moving the planetary gears and inking roller. As shown in Fig.

. 26, the arm 19 swings with a slotted hub 9|. A

key 9|" fits in the slot of the hub SI and is attached to the arm 18. When the arm 18 is pushed back against the leaf spring 9|, the key can swing in the slot of the hub 3| without moving the arm 19 until the roller can pass under the arm 18.

The ink holding roll 81 forms a reservoir of ink for inking the ribbon and the roll 81 may be formed of felt or other suitable material which can hold a supply of ink so that the roll 81 automatically replenishes the ink of the ribbon 88. The ribbon 88 automatically picks up sufficient ink-from the roll 81 for inking each ticket as it passes through the ticket holder 38.

As the handle is pulled outwardly, a wiper arm 82 (Fig. 11) is reset. The wiper arm 82 serves to eject envelopes from the slot or recep tacle 38. As shown, the wiper arm is pivoted to the stationary framework of the depository as shown in Fig. 13 and swings through the slot 38 following imprinting of a package or envelope to eject the package or envelope from the slot 38. A finger or actuator arm 93 (Figs. '7 and 13) serves to actuate the wiper near the end of the closing stroke of the handle 32. As shown in Fig. 7, the actuator arm 93 is actuated by a spring finger 94 which in turn is attached to a right segment arm 35 which can be pulled in and out by the handle 32. As the handle 32 and segment arm 35 are pulled outwardly, the finger 84 releases the surface of the receptacle or slot 33. The member 31 isattached to plates 91' (Fig. 21) which are integral with and extend inwardly from the front panel 33 so that the member 93 is stationary. A plate 9'8" attached to upstanding portions .of

.the member 97 forms the upper surface of the receptacle or slot 38, as shown in Figs. 14 and 15. As the handle 32 is pulled further out, the spring finger 94 moves outwardly to the position shown in Fig. 8, passing over a beveled surface 91" (Figs. 8 and 9) of a pivoted hammer actuator arm 93.

As the handle 32 is pulled outwardly, a spring pressed pin 99 which extends through the right segment arm 95 rides over a bevel I3! (Figs. 9a and 9b) on a pivoted yoke I92 and seats between the arms of the yoke.

At the same time. as the handle 32 is pulled outwardly, a gear segment 893 (Fig. 8) rotates a pinion I04 (Figs. 8 and 13) and swings a circular cam its through an angle of a little more than 180 degrees. The gear segment IE3 is attached to radial arms I06 which swing with and are integral with the segment arm 93. A pawl spring I97 (Fig. 13) attached to the cam B33 swings with the cam mt between a position shown in Fig. 15 and a position shown in Fig. 28, passing over one of three spaced ratchet pins 39 attached to a ticket drive sprocket wheel I39. As shown in Fig. 1'7, each of the pins I08 has a beveled or slanting outer surface I I I, which cooperates with a beveled surface I I2 of the pawl spring to permit the pawl spring to ride over the ratchet pin.

As shown in Fig. 19, the ticket drive wheel includes a plurality of radial outwardly extending posts or sprockets I I3 which can engage perforations H4 in the tickets (see Fig. 23). During the handle opening stroke, the ticket drive sprocket wheel B99 remains stationary, being held in place by a spring pressed detent H5 (Figs. and 18) which extends into one of three cam slots H3 in the periphery of a circular cam M3 attached to the ticket drive wheel.

As shown in Figs. 2 and 7, at the start of the stroke in which the handle 32 is pulled outwardly,

. a. scoop or rear door H3 is raised so that the receptacle slot is open at its lower end to permit any package or envelope therein to fall free from the slot through the rear opening thereof. However, as the handleis pulled outwardly, a pin H9 (Fig. 7) attached to the right segment arm 95 engages a slot I29 in a side wall of the scoop and swings the rear door upwardly until the rear door comes against the underside of a door sup- .port frame I2I to which the rear door is pivoted,

" 21 where the door is released. A spring I 26 (Fig.

2) pulls the door to open position. At the same time, the pin 58 (Figs. 2 and 6) moves the handle lock discs 43 into the socket 53 so that thereafter,

the handle may be pushed inwardly. As the door 34 opens, the rear door falls from the position shown in Fig. 10 to the position shown in Fig. 8 swinging with the door support frame I2I as the support frame swings in opening the door 34. The door frame I2I swings about a pivot I21 (Fig. 21), and so long as the door 34 is open, it is impossible to open the rear door, for stops I2. hold the rear door shut. Each of the stops I2! is attached to and forms a part of one of the stationary plates 91' (Fig. 8).

Finally as the handle is pulled outwardly. a ticket severing knife I3I (Figs. 11, 27 and 28) is raised to ticket cutting position. The knife is carried by a pivoted knife support plate I32. A rollerl33 attached to the knife support plate I32 rides on a cam surface I34 of the circular cam I96. and, as the cam IDS is turned during outward movement of the handle 32, the roller I33 follows the cam surface I34 to raise the knife above a ticket discharge slot I33 to the position shown in Fig. 2'7. The roller I33 is held down against the cam surface by a spring I31 which urges the knife bracket and blade downwardly.

An end of a. pivoted cam follower I33 also follows the cam surface I34. The cam follower I33 carries a transverse ticket folding plate I39 which extends through a slot in the lower wall of the ticket discharge slot 33 and, when the follower I38 is forced to the left, as shown in Fig. 27, the plate I39 extends across the ticket discharge slot, as shown in Figs. 19 and 27. A spring holds the plate I39 erect until an end of a ticket comes against it to force the plate against an arcuate surface I42 in the inner wall of the outside panel 30 to direct tickets against the arcuate surface as the tickets leave the ticket drive wheel.

Then, when the door 34 is open, a package can be inserted into the slot 33.

When the envelope 36' has been inserted in the slot 36, as shown in Fig. 10, the handle is pushed inwardly whereupon the indicia of the ticket in the ticket slot 38 are imprinted on the envelope and the depository issues the ticket as a receipt for the deposit.

As the handle 32 is pushed inwardly, the first operation is the closing of the door 34. A roller I44 (Fig. 8) attached to the right side of the door support frame I2I rides upwardly along a cam surface I46 on the right segment arm to swing the frame and door 34 shut so as to prevent removal of the envelope after it has been stamped in the depository. When the door 34 is shut, springs I41 (Fig. 11) force the door locking plate I23 into a groove I48 (Fig. 21) in the door 34 to hold the door closed. After the door 34 has been closed. it is not possible to reopen the door 34 until after the handle 32 has be n pushed fully in, for the one-way mechanism including the discs 48 (Figs. 4 and 6) already described prevents the handle 32 from being pulled outwardly once it has started in.

As the handle is pushed inwardly the spring finger 94 (Fig. 10) comes against the hammer release or actuator arm 93 and releases a spring loaded hammer I49 so that the hammer I49 can come against the envelope 36 to force the envelope against the indicia on the ticket in the ticket slot 36. As shown in Fig. 19, the hammer is loaded by a spring I5I attached to the upper wall of the slot 36. The hammer is held upwardly by a hammer support arm I52 (Figs. '7 and 10) which is pivoted to the front panel. A hammer support segment I53 which swings with the hammer support arm is provided with a shoulder I54 for abutting a cooperating shoulder I56 on the hammer release arm, and, when the spring finger 94 reaches the position shown in Fig. 10 the hammer release arm is raised to release the hammer so that the hammer falls with a sudden blow. As shown in Fig. 19, a plate I56 overlies the spring II and pre-loads the spring. The hammer I49 may be provided with a resilient head I56" so that the weight of the blow is spread over the portion of the envelope in contact with'the ticket indicia.

A weight I51 is slideable along a rod I58 which connects the hammer head to the hammer support arm I52. The weight acts as a shock absorber or damper to prevent the hammer from rebounding repeatedly against the envelope 36. Leather washers or the like I59 also are slideable along the rod I58 to help absorb and dampen the hammer rebound. The hammer is moved downwardly by spring I5I at a higher rate of speed than the speed at which the weight I51 falls by gravity so that when the hammer hits the envelope 36, the weight will be in the position shown in Fig. from which it meets the hammer on its rebound and prevents the spring rebounding above its neutral position. Thus, the

weight prevents the hammer from reversing and striking the envelope 36 a second time so that only a single impression of the indicia is made on the envelope. Following the hammer blow, the spring arm I5I raises the hammer to a neutral position at which the spring arm is substantially unfiexed and the hammer is above and away from the envelope. The construction of the hammer actuating mechanism, as shown, provides a heavier blow or impact on a relatively thick envelope than is received by a relatively thin envelope, for after the spring passes its neutral or straight position, the spring retards the downward speed of the hammer. Thus, a thick envelope, which requires a heavier impact to force it against the inked ticket indicia, receives a heavier impact than does a thin envelope which requires a lesser impact.

As the handle 32 is pushed inwardly, the spring-pressed pin 99 (Fig. 8) causes the yoke I02 to swing from the position shown in Fig. 8 to that shown in Fig. 9a. A shaft I6I (Fig. 14), which extends through the pivot about which the door support frame I2I swings, is attached to and turns with the yoke I02. A pawl release arm or discriminator I62 is rotatably mounted upon the shaft I6I and is linked to rotate therewith by a spring loaded friction clutch formed by spherical spring segment I64. The discriminator arm I62 swings with the yoke I02 and shaft I6I so long as the discriminator arm is not retarded.

As shown in Figs. 15 and 18, the discriminator arm I62 can swing down through a slot in the lower wall of the receptacle 36 to the position shown in dot-dash lines in Fig. 15 at 52:: where it is in contact with one of the pins I08. However, if an envelope is in the slot 36, as shown in Fig. 18. the envelope catches the discriminator arm I62 and prevents the arm from swinging against the pin I08. If an envelope is in the slot 36 as shown in Fig. 18, when the pawl spring I61 swings counterclockwise, the pawl spring picks up the pin I08 to cause the cam H6 and sprocket wheel I09 to rotate with the pawl spring I61. However, if there is no envelope in the slot 36, the discriminator arm I62 swings against the pin I06 (as shown in Fig. 15), and a beveled surface I66 (Fig. 16) at the end of the discriminator arm I62 permits the pawl spring I! to ride over the pin I08 without engaging the pin, where= by if no envelope is in the slot 36, the sprocket wheel I09 cannot be advanced and no ticket can be issued, but when an envelope is disposed in the slot 36, the pawl spring I01 engages one of the pins I08 and the ticket sprocket wheel I09 turns with the cam wheel I06 for one-third revolution.

As the ticket sprocket wheel is advanced, a ticket is fed toward the ticket slot 33 (Figs. 19, 27 and 28) However, the transverse ticket folding plate I39 causes the ticket to follow the arcuate surface I42 at first so that the ticket starts to fold.

As the ticket is fed against the arcuate surface I42 (Fig. 27) the cam follower I38 (Fig. 11) swings back to the right withdrawing the ticket folding plate I39 from the ticket slot (Fig. 28) so that the ticket can fold and extend outwardly through the ticket slot 33. As shown in Fig. 23, each ticket is provided with a line of weakening I66 upon which the ticket readily folds. As the ticket is delivered, it is folded upon itself along the line of weakening I66 with the inked indicia inside so that the ink on the indicia is not exposed but is covered by the folded ticket. The ticket is feed out of the slot 33 with the line of weakening I66 first, and the depositor receives a ticket in which no inked surface is exposed.

As the handle 32 is pushed further inwardly, a pin I61 (Figs. 9a and 9b) attached to the right segment arm comes against the lower side of the yoke I02 and causes the yoke to swing back to the position shown in Fig. 8. As the yoke returns, the discriminator arm I62 is raised until it comes against a pin I68 (Fig. 11) which acts as a limit for resetting the discriminator arm.

Meanwhile, the pin II9 (Fig. 10) is advanced toward the slot I20 in the rear scoop or door and, as indicated most clearly in Figs. 7 and 10, the pin II9 engages the slot and, as the handle is pushed further in, the pin II9 swings the rear door to fully open position shown in Fig. 7 to release the envelope from the slot 36 so that the envelope can fall into a vault I69, indicated schematically in Fig. 2. The vault may be provided with appropriate bafiles and the like of usual form to prevent fishing for packages. The rear door or scoop H8 and the door 34 are both mounted on the door support frame I2I. The rear door is held closed as long as the front door is open and as the front door is being opened or closed, the rear door only swings between the positions shown in Figs. 8 and 10 in both of which the rear door is held closed by the stops I28. Only when the front door is fully closed does the pin I I9 catch the rear door to swing the rear door open, as shown in Fig. '7.

As the handle 32 is pushed inwardly, the spring finger 94 engages the wiper actuator arm 93 to swing the wiper 92 through the slot 36 to force the envelope from the slot. As shown in Fig. 13, the wiper 92 is supported on a pivoted rod Ill. The wiper is formed of a rubber sheath I12 which covers a tightly wound coil spring I13. The rubber may be vulcanized to the convolutions of the spring so that the spring and rubber sheath form a strong yet yieldable whole of great durability capable of exerting a strong yet resilient sweeping force for clearing envelopes from the receptacle slot 36.

As the handle 32 is pushed further in, a roll I14 (Figs. 7 and 8) on the right segmentarm 95 engages a hammer reset finger I16 which is attached to the hammer support arm and raises the hammer reset finger and support arm to cock or reset the hammer in position for the next cycle of operation of the depository.

' As the cam I06 (Fig. 11) swings back counterclockwise while the handle 32 is pushed in, the sprocket wheel I09 swings with the cam I06 provided an envelope or package is in the slot 35. The circular cam 6' turns with the sprocket wheel I09. As shown in Fig. 15, the circular cam IIG of the wheel I09 supports the knife after the cams start turning together. The knife is supported by a cam follower I19 which follows the surface of the cam I I6 of the sprocket wheel, and the knife is supported until the ticket has been folded and discharged through the ticket slot 33. Then the cam follower I19 rides into one of the V-shaped slots I I6 to permit the knife I3I to fall abruptly severing the ticket. As shown in Fig. 28, the knife blade shears the ticket upon the edge of a shear plate I80 which forms the bottom of the ticket discharge slot. As shown in Fig. 23 the tickets may be provided with cutaway side portions I8I opposite alternatesprocket perforations, and the tickets are separated and cut off at the position of these cut-away side portions. As the knife blade and knife support bracket fall, their fall is retarded by a rubber bumper I80 (Figs. 27 and 28) which catches the falling knife bracket and supports the knife, absorbing the blow of the knifes fall.

Finally, when the handle 32 has been pushed fully in, the one-way mechanism discs 48 (Fig. 4) rise into a slot 6| which locks the handle in closed position until the discs of the one-way stop mechanism are released.

Operation of the depository is simple and will be clear from the foregoing detailed description and the drawings. The depositor first inserts a coin through the coin opening 3I to release the one-way mechanism. Then he can pull the handle 32 outwardly to cause the inking of a receipt ticket. When the handle 32 is pulled fully out, the door 34 opens to give access to the receptacle slot 36. Then he inserts an envelope in the slot and pushes the handle 32 in to cause the depository to print the tickets indicia on the envelope and issue the ticket as a receipt. The receipt ticket forms a record of the deposit and bears the same indicia as the envelope. If a package becomes lodged in the slot, the coin operated door release is rendered inoperative so that a subsequent depositor cannot reach the lodged package and the depository cannot be actuated until the lodged package is removed. On the other hand, if the door is opened and closed again without the insertion of a package or envelope, no receipt ticket is issued.

In other receipt issuing depositories which have been proposed heretofore, there is no positive provision of means for insuring that the same indicia appear both on the receipt ticket and on the package or envelope deposited therein. With the present depository, the receipt is the same ticket which acts to print indicia on the envelope or package deposited in the depository so that the ticket issued always bears the same indicia as the package or envelope.

The operation of the discriminator arm I62 prevents the issuance of a ticket unless the envelope or package is disposed in the slot 36, for the discriminator arm I62 prevents the pawl spring I01 from engaging the pin I08 (Fig. 15) when the slot 36 is empty. Only when an envelope or package is in the slot 36 is the discriminator arm I62 held away from the pins I08 so that the pawl spring can engage one of the pins the handle'fro'm being pulled outwardly once it has started in. When the handle is pushed fully in, the discs 48 rise into the slot BI locking the handle in. The discs cannot be moved to release the handle if a package is lodged in the slot 36, for, as shown in Fig. 20, the arm 83 is caught by the package to prevent the arm 44 from being swung into position to release the depository.

The arm 34 and the rear door or scoop I I8 are both mounted on the door support frame I2 I, and when one of the doors is open the other is held closed so that the slot 36 is closed at one end or the other at all times.

The depository is wholly mechanical in operation requiring no electrical or hydraulic connections.
